  • LT Environmental, Inc. & RPI Group Celebrate Closure at High Profile Site

    It is hard to believe that RPI Group has been exceeding client remediation goals for almost 15 years. This newsletter celebrates, perhaps, the greatest thing that my colleagues have accomplished “to date”. This large and extremely high profile site had a combination of ubiquitous TCE contamination, varying and challenging lithology, DNAPL “surprises” and a ...

  • NRCC-MEF: Visit to University of Naples “l’Orientale”

    On Friday 1 April, the fifteenth NATO Regional Cooperation Course (NRCC-15) and members of the Middle East Faculty (MEF) travelled to the University of Naples “L’Orientale”. The aim of the visit was to attend a lecture and discussion on the subject of “Migrations through Mediterranean Corridors”. The Rector, Elda Morlicchio, warmly welcomed the attendees before the ...

  • Characterizing DNAPL source zones for remedial performance assessment

    Chlorinated solvents have been used extensively in industry and are common groundwater contaminants. Their limited aqueous solubility often leads to the presence of dense non-aqueous phase liquid (DNAPL) source zones, which may persist due to mass transfer limitations from the DNAPL to groundwater. While recent research effort has been directed to the development of effective source zone ...

  • Supersaturated Water Injection

    Passive Gas infusion is a patented technology that efficiently dissolves high concentrations of CO2 into water at elevated pressures. Supersaturated Water Injection (SWI) is an effective technology for NAPL recovery. CO2 supersaturated water injected into the subsurface results in the nucleation of CO2 bubbles at and away from the injection point. As the supersaturated liquid flows through the ...

  • MetLife foundation and the national association of area agencies on aging honor older volunteers in Washington, DC

    Today, the National Association of Area Agencies on Aging (n4a) announced recipients of the 2010 MetLife Foundation Older Volunteers Enrich America Awards. The program, now in its eighth year, honors the exemplary contributions of older volunteers and promotes volunteering among older adults nationwide. The award-winning volunteers, who range in age from 59 to 95 years, were in Washington today ...

  • Volatile dense chemical liquids in groundwaters can produce slowly bubbling gas flow

    Despite decades of research, the cleanup of soil and groundwater contaminated by dense non-aqueous phase liquids (DNAPLs) used in numerous industrial applications remains a daunting challenge. These compounds, including degreasers, dry cleaning fluids, creosote, solvents and coal tar, when present below ground can generate hazardous concentrations for decades to centuries as they dissolve into ...

  • Waste crisis erupts in Naples

    Police have withdrawn from the entrance of a defunct waste dump that officials say will be reopened to take garbage that has piled up by the ton in the streets of Naples. Although residents of the southern port city are upset by the piles of trash, they have also blocked plans to reopen the dump in the Pianura neighborhood of Naples. About 500 demonstrators clashed with police at the the ...
